COENAGRIONIDAE “Coenagrioninae” (Kirby, 1890) Coenagrionidae is the largest family of damselflies in the world with more than 130 genera and over 1200 species. These totals are based on recent molecular phylogenetic studies indicating that the Pseudostigmatidae and New World Protoneuridae belong in the Coenagrionidae (Dijkstra et al. 2014).
